Looks like all the show is about Xia Zi Xun and Mantian trying to kill the FL.
Really, all the drama it's about they being ridiculous obsessed with hurting the FL because of the ML.
It's so bad, there must be a thousand dialogues about this. Especially related to the obsession of Zixun, he just allowed her to do all those things. And he knew Martian was trying to hurt the FL and did nothing!
And the ML is just a moron, never steeping up when needed. If he had a voice and stood up most of the problems wouldn't have happened.
He was also treating the FL really bad in so many moments, blaming her or avoiding her. Just take the part of that instrument for the demon clan, he left her take the blame, he could just say that he allowed her to take it.
Ah, and the romance? Pretty much non-existent.

The only good thing is the production and OST.
